WWTBAM Bored

I'm having problems getting onto any of the Disney/ABC/Go.com sites. I have a Mac now, but I can't get it on the Dell either. I can sometimes get to the home page, like with WWTBAM, but I can't register for the prize. Nor can I sign up for Travel trivia at the Live with regis site. Anybody have a suggestion?

No problems getting into any of the sites from here. Maybe it's your ISP. No suggestions, though. Sorry.
